An optical mouse is a computer mouse which uses a light source, typically a

light-emitting diode (LED), and a light detector, such as an array of photodiodes, to detect movement relative to a surface.Variations of the optical mouse have largely replaced the older mechanical mouse design, which uses moving parts to sense motion.. The earliest optical mice detected movement on pre-printed ...
